Issues with WiFi

[ant_27485]

Hi i got a raspberry pi model a and model b
I have the model a working fine

but i am having issues with the model b

Im using the same wifi dongle and it occasionaly works but then i get the Wifi supplicant error

I have tried different dongle and a different pi

any help would be good

the issue is intermediate

start with the basics

lsusb
ifconfig -a
dmesg | grep usb
sudo killall ifplugd
route -n
ping -c 3 192.168.1.1 # assuming that's your home gateway
ping -c 3 173.194.41.97 # google's ip address
ping google.com

Er ... no!

To diagnose what's wrong I'd need the output from all of those strange arcane commands.
It's exactly what I do if my RPi doesn't want to play nicely with my network.

Welcome to the land of a real operating system rather than the consumer computers you're used to.
